Starting the planning for your first Self Assessment? Don’t leave everything until January.
If you’ve registered for Self Assessment, the next step is getting your information together.
Here’s a good place to start:
📥 Income - what you’ve earned during the tax year
💷 Expenses - your allowable business costs
🏦 Bank records - statements and transactions to support your figures
📄 Relevant documents - anything else you may need to report
💰 Other income - for example, income outside your main business
You don’t need to have your tax return completed today. But getting your records together now can make the process much easier when you come to file.
If this is your first Self Assessment, starting early can make January feel a lot less daunting.
